New York Practice Construction Signs

According to the manual, what is the lowest speed limit that can be posted in a New York work zone?

  1. A.
    As low as 25 MPH Correct
  2. B.
    Same as the road's normal limit
  3. C.
    Never below 40 MPH
  4. D.
    Set by the flag person, not by sign
The Why

The answer is "As low as 25 MPH"

The manual allows a work-zone speed limit as low as 25 MPH. Option C is where the 40 comes from: the manual prints '25 MPH (40 km/h)' side by side, and a driver who skims past the km/h label carries the 40 forward as an alternate MPH figure.

Why the others miss

The traps in the wrong answers

B. Same as the road's normal limit

Work zones lower the limit; that is the point of posting a work-area limit. This answer falls back on the surrounding road's default when no work-zone number comes to mind.

C. Never below 40 MPH

The 40 in '25 MPH (40 km/h)' is a metric conversion of 25, not a separate speed. This answer reads the parenthetical km/h figure as if it were an alternate MPH limit.

D. Set by the flag person, not by sign

Flag persons control the flow of traffic, but posted speed limits come from signs, not from flaggers. This answer blends the flag person's authority to stop and start traffic with the authority to set a speed.
